“Sometimes captured from the great arboreal freedom of their jungle homes, monkeys are closely confined in cages only three or four feet square. … They can never sit or lie down on a flat, soft or yielding surface. Little wonder that by the time they are needed for the knife or the needle they are so crazed or inert that they are no longer representative examples of animal life. Psychologists who study the behaviour of thousands of such creatures annually, rarely make allowances for the fact that their pathetic subjects have been so deprived that they have become more like monsters than animals. Many people who have experienced close affectionate relationships with individuals of other species testify to the considerable potential for emotional and intellectual development that animals have. When properly cared for a pet dog or cat can develop great subtleties of behaviour that the laboratory animal never shows. Those who have been fortunate enough to closely observe unfrightened animals living in the wild are often struck by the complexity and richness of the life they lead. These positive pleasures the laboratory animal never knows; for him the same four white walls and the smell of disinfectant.”

“Three times in my life I have been captured: by the orphanage, by school, and by the Army. I was four years in the orphanage, seven or eight in school, and three in the Army. Each seemed forever, though. But I'm mistaken. The fact is I was captured only once, when I was born, only that capture is also setting free, which is what this is actually all about. The free prisoner.”

“If, in spite of the fact that all these attributes have been faithfully handed down unaltered for hundreds of generations, we are to believe that, in the course of time, they have all diverged from one common stock, how shall we resist the arguments of the transmutationist, who contends that all closely allied species of animals and plants have in like manner sprung from a common parentage, albeit that for the last three or four thousand years they may have been persistent in character?”
